Safe converter operation requires that the equipment is mounted and
commissioned by qualified personnel taking into account the warning
information provided in these Operating Instructions.
The general and domestic installation and safety regulations for work
on electrical power equipment (e.g. VDE) must be observed as well as
the professional handling of tools and the use of personal protective
equipment.
Death, severe bodily injury or significant material damage could result if
these instructions are not followed.
When installing the units, it must be observed that the mains
connection is located at the bottom section of the unit and the DC link
connection at the top section of the unit.
The rectifier unit and the inverters can be mounted flush with each
other.
In order to ensure an adequate supply of cooling air, a clearance of 100
mm must be left at the top of the unit and at the bottom of the unit
respectively to components which may considerably affect the flow of
cooling air.
When mounting in cabinets, the cabinet cooling must be designed
according to the power loss. Please refer to the Technical Data in this
regard.
♦ Foreign particles
The units must be protected against the ingress of foreign particles
as otherwise their function and operational safety cannot be
ensured.
♦ Dust, gases, vapors
Equipment rooms must be dry and dust-free. Ambient and cooling
air must not contain any electrically conductive gases, vapors and
dust which could diminish the functionality. If necessary, filters
should be used or other corrective measures taken.
♦ Cooling air
The units must only be operated in an ambient climate in
accordance with DIN IEC 721-3-3 Class 3K3. For cooling air
temperatures of more than 45 °C (113 °F) and installation altitudes
higher than 1000 m, derating is required.
